SPECIFICATION forming part of Letters Patent No. 767,402, dated August 16, 1904.

- Application filed October 2, 1903.

To all whom it may concern:

Be it known that I, FREDERICK GLAssUr, a

citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Devices for Inflating Pneumatic Tires, of which the following is a specification.

This invention relates to devices for inflating pneumatic tires, and is especially designed to be attached to and carried by motor-cars and like vehicles wherein rapid inflation and great compression is required.

The invention consists in the general arrangement and combination of the several parts, as will be hereinafter described, illustrated in the drawing, and particularly set forth in the claims.

The figure illustrated in the drawing is a perspective view of the improved device, showingthe same applied to one of the side beams and the underframe of an ordinary motor-car.

In the drawing, the numeral 1 indicates a side beam of a motor-car, 2 a portion of the underframe which supports the engine and gearing, (not shown,)v and 3 the engine flywheel mounted on the main shaft 4.

The improved device is supported by brackets 5 and 6, which are secured to the side beam 1 and underframe 2, as shown. Rotatably mounted in the bracket 5 is a shaft 7, carrying at its upper end a gear-wheel 8 and on its lower end a fixed disk 9. v

The numeral 10 indicates a slotted bar or slide which is adapted to be reciprocated in brackets or guides 11 11, carried by brackets 12 12, secured to the frame of the vehicle.

Attached to the forward end of the slotted bar 10 is a piston-rod 13 of any well-known type of compression-pump 14, supported in brackets 15 15, secured to the side beam 1. The rotary disk 9 is provided with a pin 16, carrying a roller 17, and is adapted to set and work in the slot 18 of the slotted bar 10, as shown, whereby said slotted bar and the attached piston is reciprocated through the medium of the disk 9 when power is applied to the gear-wheel 8.

Mounted on the bracket 6is asliding bearing 19, in which is journaled a short shaft 20,

Serial'No. 175,412. (No model.)

carrying at one end a pinion 21, meshing with the gear-wheel 8, and at the other end a pulley or friction-wheel 22, which is adapted to be thrown into contact with the fly-wheel 3, as is evident, for a purpose to be hereinafter stated. Projecting from the bracket 6 is an upstanding. car 23, in which is mounted a screw-threaded draw-bar 24: and is operated by a suitable crank or key 25.

In the operation of the invention the flexible tube 27 is attached to the valve of the tire in the usual manner, and the pulley or friction wheel 22 is forced and held in contact with the fly-wheel 3 by means of the screw-threaded draw-bar 24:. When the pulley or friction-wheel is brought into contact with the fly-wheel, rotary motion will be imparted to the disk 9 through the medium of' gear 8 and pinion 21, thereby causing the slotted bar 10, which is connected with said disk and the attached piston to be reciprocatedto operate the pump. When the inflation of the tire is complete, the pulley or friction-wheel is withdrawn from contact with the fly-wheel by means of said draw-bar, as will be evident.

If it is desired to inflate more than one tire at a time, it will be evident that this may be accomplished by providing the flexible tube with one or more branches to carry the air from the pump to the several tires to be inflated.

It is evident that variations and modifications of the present invention may be made without departing from the spirit or scope of this invention. It is therefore desired that the present invention be not limited to the precise construction herein shown.

Having thus described my invention, what I claim is 1. The combination with the piston of an air-pump, of a reciprocatory bar having approximately a V- shape slot therein, a rotatable shaft carryingadisk havinga pin arranged to operate in said slot, a gear-wheel and pinion, and means imparting motion to the rotatable shaft and disk.

2. The combination with the fly-Wheel of an engine, the piston of an air-pump, and mechanism reciprocating said piston, of a sliding bearing, a shaft carrying a friction-pulley, and means for throwing said pulley into and out of frictional contact with the fly-wheel.

3. The combination with the piston of an air-pump, of a reciprocatory bar provided with a suitable siot, a disk mounted on a rotatable shaft and provided-with a pin arranged to operate in said slot, a gear-wheel and pinion imparting motion. to said shaft, a sliding bearing, a shaft mounted in said bearing and carrying a friction-pulley, a fly-wheel, and means for throwing said friction-pulley into and out of engagement with the fly-wheel.

4. The combination with a frame of a mo tor-Vehicle having pneumatic tires, of an airpump supported by said frame, means adaptcd to connect said air-pump with the pneumatic tires, a reciprocating bar connected with FREDERIGK GLASSUP.
